Explanation: Cyrenoidea belongs to the biological class Bivalvia, not Gastropoda. Bivalves are characterized by their two-part hinged shell.

Explanation: The established taxonomic structure of the Cyrenoidea superfamily includes the families Cyrenidae, Cyrenoididae, and Glauconomidae.

Explanation: The established taxonomic hierarchy places Cyrenoidea within the Order Venerida, Phylum Mollusca, and Class Bivalvia.

Explanation: In biological taxonomy, the rank of 'superfamily' is hierarchically above 'family' and below 'order'.

Explanation: Organisms classified under Phylum Mollusca are invertebrates, lacking a backbone, and often possess a shell.

Explanation: In biological classification, the order Venerida is a higher taxonomic rank than the superfamily Cyrenoidea, meaning it encompasses Cyrenoidea and other related superfamilies.

Explanation: The primary classification of Cyrenoidea is a superfamily of freshwater bivalves, belonging to the order Venerida.

Explanation: The superfamily Cyrenoidea is classified under the biological order Venerida, which comprises a significant group of bivalve mollusks.

Explanation: The officially recognized families within the Cyrenoidea superfamily are Cyrenidae, Cyrenoididae, and Glauconomidae. Corbiculidae is not listed as one of these.

Explanation: The complete scientific classification provided places Cyrenoidea within Phylum Mollusca, Class Bivalvia, and Order Venerida.

Explanation: Classification as 'Class Bivalvia' indicates that Cyrenoidea are mollusks characterized by having two hinged shells.

Explanation: Classification within Phylum Mollusca signifies that Cyrenoidea are invertebrate animals, a diverse group that frequently exhibits a shell.

Explanation: The scientific literature indicates that J. E. Gray formally classified the superfamily Cyrenoidea in the year 1840.

Explanation: The family Glauconomidae was described by J. E. Gray in 1853, not by H. Adams & A. Adams.

Explanation: The synonym Corbiculoidea was described by J. E. Gray in 1847, not by H. Adams & A. Adams in 1857.

Explanation: J. E. Gray described the family Cyrenidae in 1840. The year 1857 is significant for H. Adams & A. Adams describing the family Cyrenoididae and the synonym Cyrenoidoidea.

Explanation: The initial classification of the superfamily Cyrenoidea is attributed to J. E. Gray.

Explanation: J. E. Gray initially classified the superfamily Cyrenoidea in the year 1840.

Explanation: The family Cyrenoididae was described by the researchers H. Adams & A. Adams.

Explanation: H. Adams & A. Adams described the family Cyrenoididae in the year 1857.

Explanation: The synonym Corbiculoidea was described by J. E. Gray.

Explanation: Corbiculoidea is recognized as a synonym, representing an alternative scientific name previously applied to the superfamily Cyrenoidea.

Explanation: The hatnote clarifies that the article pertains to the superfamily Cyrenoidea, distinguishing it from the genus Cyrenoida, rather than stating the article is about the genus.

Explanation: Listing synonyms is crucial for scientific clarity, as it helps identify alternative names used in different literature or classification systems, ensuring comprehensive understanding.

Explanation: Cyrenoidoidea is listed as a synonym for the superfamily Cyrenoidea, not as a family within it. It represents an alternative scientific name previously used for the superfamily.

Explanation: Cyrenoidoidea is listed as a synonym for the superfamily Cyrenoidea, indicating it is an alternative scientific name previously or concurrently used for this taxonomic group.

Explanation: Listing synonyms serves to provide alternative scientific names that have been used for the superfamily, ensuring clarity and completeness in scientific literature.

Explanation: The Cyrenoidea superfamily encompasses bivalves found in marine, brackish, and freshwater environments, not exclusively marine ones.

Explanation: The Cyrenoidea superfamily comprises approximately 60 or more known living species, exceeding the threshold of fewer than 50.

Explanation: Estimates indicate that the Cyrenoidea superfamily comprises approximately 60 or more distinct living species.

Explanation: Species within the Cyrenoidea superfamily inhabit marine, brackish, and freshwater environments. Subterranean caves are not mentioned as a habitat.

Explanation: A referenced research paper published in 2023 specifically addresses the revision of the Cyrenoidea superfamily, employing methods such as species delimitation and phylogenomics.

Explanation: The Digital Object Identifier (DOI) 10.1071/is23015 corresponds to the 2023 research paper concerning the revision of the Cyrenoidea superfamily.

Explanation: The journal 'Invertebrate Systematics,' which published the referenced 2023 study on Cyrenoidea, is identified by the International Standard Serial Number (ISSN) 1445-5226.

Explanation: Species delimitation is the process of identifying and defining distinct species, which may involve analyzing genetic data such as mitochondrial genomes, but is not solely limited to analyzing the complete mitochondrial genome.

Explanation: Multi-locus phylogeny is a methodology that employs DNA sequences from multiple genes (loci) to reconstruct and analyze the evolutionary history and relationships among organisms.

Explanation: The inclusion of numerous taxon identifiers (e.g., from WoRMS, CoL, NCBI) indicates that Cyrenoidea is a recognized taxonomic entity with extensive cataloging across major biological databases.

Explanation: The 'Taxon identifiers' section serves to provide unique identifiers that link to external databases, facilitating access to more comprehensive information about the Cyrenoidea taxon.

Explanation: The taxon identifier corresponding to the World Register of Marine Species (WoRMS) entry for Cyrenoidea is 489089.

Explanation: The 2023 research paper concerning the revision of the Cyrenoidea superfamily was published in the journal 'Invertebrate Systematics'.

Explanation: The Digital Object Identifier (DOI) for the 2023 research paper on Cyrenoidea is 10.1071/is23015.

Explanation: Multi-locus phylogeny is a method used to study evolutionary relationships by analyzing DNA sequences derived from multiple genes or genetic markers.

Explanation: The infobox for Cyrenoidea displays an image of a bivalve (Polymesoda notabilis), not a marine snail.

Explanation: A 'stub' notice signifies that an article is brief and incomplete, inviting expansion, rather than indicating a comprehensive overview.

Explanation: The concise 'short description' provided for Cyrenoidea is 'Superfamily of freshwater bivalves', not 'Superfamily of marine snails'.

Explanation: The term 'bivalve' signifies that these organisms are mollusks possessing a shell composed of two hinged parts, not a single, unhinged shell.

Explanation: The term 'brackish' describes environments characterized by a mixture of fresh and saltwater, typically found where rivers meet the sea.

Explanation: Taxonomy is the scientific discipline concerned with the classification, naming, and identification of organisms based on their characteristics and evolutionary relationships, not primarily their geographical distribution (which is biogeography).

Explanation: The term 'biota' in the infobox refers to the collective animal and plant life associated with the Cyrenoidea superfamily.

Explanation: The infobox image for Cyrenoidea displays a bivalve, specifically identified as a type of clam (Polymesoda notabilis).

Explanation: The term 'bivalve' signifies that these organisms are mollusks possessing a shell composed of two hinged parts.

Explanation: The term 'brackish' describes aquatic environments characterized by a mixture of fresh and saltwater.
